🔍 What Is a QR Code Reader?

A QR Code Reader is a tool that allows you to scan, detect, and decode the information stored in a QR code, either:

• 📷 Through your device’s camera
• 🖼️ Or by uploading an image file

Once scanned, the tool instantly reveals the embedded content, such as:

• Website URLs
• Plain text
• Emails or phone numbers
• Wi-Fi credentials
• Contact cards (vCard/MeCard)
• Calendar events

• 📁 Upload QR images from emails, PDFs, or design files
• 🖥️ Use desktop or laptop camera for scanning
• 🧪 Decode QR content before printing or publishing
• 🔐 Ensure a QR leads to a trusted link before scanning on mobile

Perfect for:

• Designers
• Developers
• Marketers
• Teachers
• Anyone receiving a QR via digital media
